What is a computed tomographer?

A computed tomographer uses a number of thin, rotating x-ray beams and computer technology to create cross sectional (axial) images of the human body.

In computed tomography (CT), the computer measures the intensity of x-rays, which are transmitted through the patient, and displays the information as an image on a monitor.

CT technologists use these innovative technologies to create diagnostic images by determining and setting technical parameters, and positioning the patient to create images that accurately display anatomy and pathology. In addition to technical expertise and computer literacy, excellent communication skills are essential for CT technologists who are responsible for patient education, instruction, and safety.
